UNITED STATES PATENT OFFICE.

JOHN KAYLOR, or DECATUR, ILLINQIs' CHECK-ROW ATTACHMENT FOR CORN-PLANTERS.

SPECIFICATION forming part of Letters Patent No. 274,123, dated March 20, 1883.

Application filed June .20, 1882. (ModeL) T all whom it may concern Be it known that I, JOHN KAYLOR, a citizen of the United vStates, residing at Decatur, in the county of Macon and State of Illinois,

have invented a new and useful Improvement in Check-Row Attachments for Corn-Planters, of which the following is a specification.

My invention relates to certain new and useful improvements in check-row attachments IQ for use with and to be operated by a wire or cord stretched across the field; and it consists in the employment of a vertical shaft mounted upon the transverse beam and supported by a bracket or frame of suitable dimensions, and

1 provided with two ratchet-disks having teeth formed on the side or plane of said disk, on a line across the center, a bevel-pinion fitted to revolve freely on the vertical shaft between the ratchet-disks, and provided with a pawl 2o fitted loosely in a hole in said pinion vertically,

and adapted to engage with the teeth of the ratchet wheels or disks. The device being so constructed and operated by a bevel segmentgear mounted upon an oscillating transverse shaft, by its engagement with the pinion on the vertical shaft an intermittent rotary motion is imparted to the said v'ertical shaft through the medium of the pawl and ratchet, in the manner and for the purpose hereinafter described, reference being had to the accompanying drawings, which form a part of this specification, and in which Figure 1 is a side elevation of the device complete. Fig. 2 is a plan of the ratchet-disk. Fig. 3 is a plan of the ratchet-disk which is cast with and forms a part of the shaft. Fig. 4 is an end view of the-pinion, showing the hole in which the pawl is inserted. Fig. 5 is a side elevation of the vertical shaft, showing o pinion in section, also showing wrist-pin and upper crank-disk, each of which forms a part of the cast vertical shaft. Fig. 6 represents the pawl which is designed to operate within the hole shown in the pinion, Figs. 4 and 5. 5 Fig. 7 is a plan of the segment bevel-gear. Fig. 8 represents two sections of wire joined together by a metallic loop, around the outside of which the wire passes to protect the wire from wear at the junction of the sections.

Similar letters refer to similar parts through out the several views.

In the drawings, A represents a transverse bar upon which allof the mechanism is mounted.

B is the transverse shaft, supported in suitable bearings at its ends, and provided with the ordinary forks, b b, used in other devices of its class for the purpose of intercepting the knots or'stops on the wire, and by engagement therewith an oscillating movement is imparted to the said shaft. At as near the center of the transverse shaft as practicable is provided a segment gear, 0, adapted to engage with a pinion, D, mounted loosely upon the vertical shaft E.

F is a bracket or frame, which is attached to the transverse beam in the manner shown in Fig. 1,and is adapted to support the transverse shaft, near the center, longitudinally.

The vertical shaft E, the upper ratchet, G, and the wrist-pin g and crankdisk are cast all in onepieoe. Thelowerratchet-disk,G,is made removable, and has a square hole through it which fits the square part of the shaft. It may be otherwise more rigidly secured to the shalt by a screw or pin driven into or through both 7 the disk and shaft. Still itcannot become detached if not so secured.

Theobject of the crank-disk H is apparent from the fact that it not only provides ajournal at the upper end of the vertical crankshaft, but-supports the crank or wrist-pin, and both prevents longitudinal or lateral movementof said shaft.

The connecting-rod c is hooked onto the wrist-pin and closed together, but the manner of connecting them is not new, and may be donein many ways, according to the judgment or taste of the manufacturer. The outer end of the connecting-rod is attached to a lever, c, which is pivoted to the side of the bar A to operate the shake-bar, as in other machines.

The segment-gear O is mounted upon the transverse shaft B, and secured thereto in any suitable manner, and stands in a position reverse to the forks b b, and the relative diameter 95 of the segment 0, and the pinion D is such that as the segment-gear is forced to make a quarter-revolution by the action of the knots or stops on the wire with the forks at either end i of the shaft, causes the pinion to make one-half zoo revolution, and the teeth of the ratchet G being set in a position relative to the direction of movement of the pinion that the shaft E is caused to revolve one-half round in one direction, at which point it remains, the pinion being rotated back to its former position by the tension of the spring a, provided for that pur pose and connected with the transverse shaft B and bar A, as shown. I

, The pawl I, which is fitted loosely into the elongated hole 6 in the pinion, rides up the incline ofeach tooth in the ratchetG, and is carried round this shaft far enough to allow it to drop of its own weight into the next succeeding notch, and another knot passing through the mechanism above described causes the vertical shaft E to make anotherh'alf-turn in the same direction as before. Each intermittent semicircular movement of the vertical shaft operates the shake-bar through the medium of the connecting rod and pivoted lever.

By reference to Fig. 8, m represents the metallic link or knot, and n n the wires. This loop or knot is made of cast malleable metal, and'has two short tangs, nn,which,when the wire is bent out around the outside of the metallic loop, are bent down over the returned ends of the wireand the'return end of theloop, securing them togetheraud to the bodyof said loop in the manner-shown. The metallic loop thus formed and secured to the wire protects the wire from wear at the junction of the sections. There is an offset at the end of the body tact of the two sections is upon the two metallic loops or knots, instead of on the wire, as heretofore.

I am aware that segment-gears have been used on the'transverse shaft of a check-row attachment in connection with "ertical and parallel crank-shafts; so, also, have ratchet and pawl been used; but these I do not claim, broadly but What I believe to be new, and desire to secure by Letters Patent, is-

1. In a check-row attachment for corn-planters, the combination, with the segment-gear O and pinion D, of the ratchet-disk G, wrist-pin g, and crank-disk H, cast all in one piece,witl1 the vertical shaft E, substantially as shown and described.

2. In a cheek-row attachment for corn-planters, the combination, with the segment-gear O, pinion D, and vertical shaft E, of the lower ratchet-disk, G, and pawl I, operating within a vertical hole, t, through the pinion, for the purpose of imparting an intermittent rotary motion to the vertical shaft E by an oscillating movement of the pinion and segment, substantially as and for the purpose specified.

3. The artificial knot m, made of malleable metal,in the form of a loop, with a lateral projection, n", and two lateral-extending tangs, n n, adapted to bend down past each other from opposite sides of'the body and hold the returned end of the loop and wire, as shown, to re-euforce and protect the loop formed of the sections of wire, substantially as specified.
